Subject: number of elements in array is -1?
Hello everyone,
I have a problem. I just want to print the number of elements in an
array. Here's the code:
my @scans;
my $last_host = 192.168.1.1;
while (LOGFILE) {
push (@scans, $_)
if m/$last_host/i;
}
shouldn't that put all of the results into the @scans array? I know
there'd just be a bunch of the same value.
$array[0] would equal 192.168.1.1
and $array[1] would equal 192.168.1.1
I try to show the number of elements in the array like so:
print $#scans;
But that prints -1. I know for a fact there are at least 2 entries in
LOGFILE that have an IP of 192.168.1.1.
Thanks,
Tyler Longren

I thought so. You read through the entire file, so by the time you get to
your second while loop, you're at the very end of the file. You need to

RE: get rid of the same elements in an array/hash
You will never have duplicate keys in a hash. If you try to use the same
key more than once, it will simply overwrite the previous definition:
%blah=('a_key' = 'first definition', 'a_key' = 'second definition',
'a_key' = 'YES!!')
the key 'a_key' appeared three times, but each time it overwrites the
previous definition, so in the end, %blah contains exactly one key and its
associated value:
$blah{'a_key'} eq 'YES!!'
But my guess is that you are trying to weed out duplicates in an array, not
a hash, in which case you need to do something like this:
@array=qw/one two three two one two three two four five four/;
# creates a hash using the elements from @array as keys, which eliminates
any duplicates
%hash = map {($_,'whatever')} @array;
# return the keys back to the array
@array=keys %hash;
print $_\n for @array;
__END__
Which outputs:
one
two
three
four
five
Although probably not in that order.
I just wanted to clarify that to make sure you're not trying something like
'%hash=@array'.

Actually, open is only a security hole if you allow the user to tell you what to open at the command line. i don't have the exact message in front of me, but my guess is that someone said something like: $_=STDIN; open(IN,$_|); In which case if the user entered 'rm -rf /', it would try to delete everything.

RE: Splitting a string into a Array of Arrays
You're actually very close. I would just change a couple of things.
First of all, you don't need @data as well as @rows. $element is aliased to
each element in the array as it loops, so you can re-assign right back into
the same array when you split. This will cause the loop to independent of
the order in which it reads the elements from @rows, which means you don't
need '$i' as well.
Second, when you create your nested array, you need to use [].
sub quotes
{
my $content = get_content();
my @rows=split/\n/,$content;
foreach my $element (@rows)
{
$element=[split(/,/,$element)];
}
return @rows;
}
As a matter of personal style, i prefer to take advantage of the default
variable, since i find it easier to read, though others may not:
sub quotes
{
my @rows = split /\n/, get_content;
$_=[split /,/] for @rows;
return @rows;
}
Or if you want to be COOL like Bob ;)
sub quotes {map {[split /,/]} split /\n/, get_content}
And i think in this case using 'map' would be okay, since it's going to have
to loop over the entire array anyway. Am i wrong ... ?

RE: check array element (HELP)
'%found_one' starts off empty. Everytime we find a new element, we add one
to '$found_one{$_}' via '++'. Since '++' is postfix, it occurs AFTER the
value is returned. In otherwords, '$found_one{$_}++' returns the current
value and then adds one.
Now, if the current element has never been read before, then
'$found_one{$_}' doesn't exist, and so returns false. '$found_one{$_}++' in
this case is equivalent to '$found_one{$_}=1'. In otherwords, we create an
entry in '%found_one' with key of '$_'. If, on the other hand, the element
was read before, then '$found_one{$_}' returns true. It then increments the
value and sets it equal to 2, but we don't care about that, since we've
already jumped out of the sub via return. By the end of the loop, if we
haven't returned out, we know that each element in '@_' is unique, and
'%found_one' has exactly one key for each $_ in @_, each set to 1. So, we
just return false.
Besides the fact that you introduce a lot of unnecessary variables, the only
difference between your sub and mine is that yours performs '$n log $n'
comparisons (is that right ... ?) whereas mine only performs '$n'. I don't
know enough about perl to know which method is more efficient. It could be
that the overhead involved in hashing outweighs the comparisons and array
lookups that you used. I don't know. I use this method because it's less
cluttered and makes more sense to me.
Although, if i were going to write this sub for script i were using, i would
DEFINITELY use array-refs like you did.
Oh yeah, and another thing; i think
for (my $i=0; $i$n; $i++)
is preferable to
for my $i (0...$n-1)
since the latter creates the entire array and then goes through the
elements, instead of merely going from one integer to the next.

I suppose if the luser who uses my package doesn't like what 'bark' does
s/he will just have to overload it themselves. ;)

program in C++. I kept asking the professor how to tell what one object

Subject: Re: ref problems
Hi,
I'm not sure you're quite understanding the logic of modules and packages
yet...
the idea of a module is that you use methods (subroutines belonging to a
package) to execute code
however, you're making your 'methods' attributes to an object.
This quite defeats the purpose and provides nothing in the form of
encapsulation.
(concider some ev0l subroutine you pass your object to says:
sub foo {
my $self = shift;
$self-{'speak'} = undef;
}
That would cause serious dying of your script when calling the 'method'
Maybe you should raed up on modules a bit first and OO programming in
general

following script, i get that '$this' in dog::bark is undefined. When i
think about it, this makes sense, since call $a_dog-{'speak'}() is like
saying dog::bark.
Saying
$a_dog-{'speak'}($a_dog)
on the last line would solve this problem, but it would be nice not to
have
to worry about passing itself to the function. Does anyone see any
alternatives to this?
Thanks!
#!/local/perl/bin/perl -w
use strict;
package dog;
sub new
{
my $class=shift;
my %this=@_;
$this{'speak'}=\bark;
bless \%this;
}
sub bark
{
my $this=shift;
$this || die foo: it's undefined!\n;
print $this-{'name'} says woof!\n;
}
package main;
my $a_dog=dog-new(name = 'bart');
$a_dog-{'speak'}();

RE: lost in hashes
Not hard to do when dealing with references! ;)
The problem is that you are assigning a REFERENCE TO A HASH to the HASH itself,
because you're using '{}' when assigning to %T.
$T{d4} has the opposite problem -- it needs to be associated with a SCALAR, ie. a
REFERENCE TO A HASH. '()' is a LIST, not a REFERENCE.
So, switch your '{}'s and '()'s and it should do what you want it to.
Also, when you reference some field from $T{d4}, you need to be sure to deREFERENCE it
like this:
$T{d4}-{names}
So you'll have to change that in the popup_menu.
HTH!

Actually, according to perllol the - is not required when placed between

So $T{d4}-{names} and $T{d4}{names} are equivalent.

That depends on what you're using @mylist for. If you're simply using it to

If you're creating the list element - b
push @mylist, $whatever;
you can say
$myhash{$whatever}=1;

RE: last until eof unless question
I don't think 'last until eof' will do what you think it's going to do. If
'eof' is true, then the loop exits, and if it's false then it exits anyway
because of the 'last' statement.
If you're trying to read from STDIN until you get a proper response from the
user, then do something like this:
while ($email=STDIN)
{
chomp;
last unless $email;
warn You entered a blank line: try again!\n;

This loop will skip over any blank lines the user enters.

-b = 2,
-c = 3,
-x = 24,
-y = 25,
-z = 26

RE: Getting values from a file
That's certainly the way i would do it, but if you really want them stored
in scalars instead of hashes, then you can use eval.
In other words, instead of:
$conf{$key} = $val
you can say:
eval \$$key = q/$val/
Of course if your lines all start with '-', as you posted, then you'll have
to strip that character.

RE: Variable scope and definition
'use strict' does not require that variables be preDEFINED, but that they be
preDECLARED. The my statement accomplishes this.
In fact, it doesn't matter where you DEFINE your variables. You could just as easily
say:
my ($user,$test);# or, alternatively
use vars qw/$user $test/;
and then define them later.

Subject: Re: Variable scope and definition
I am trying to understand the correct way to define
variables and their scope.
Here are two simple PERL ( test1.pl and test2.pl
)scripts. test1.pl work fine, while test2.pl does not.
Would appreciate any help in understanding why
test2.pl is complaining about Global symbols
Thanks
PN
test1.pl
#!/usr/bin/perl -w
use strict;
my $user = $ENV{USER};
my $test = Perl;
print User : $user\n;
print Test : $test\n;
test2.pl
#!/usr/bin/perl -w
use strict;
$user = $ENV{USER};
$test = Perl;
print User : $user\n;
print Test : $test\n;
The only difference in code is this:
In test1.pl, the variables are defined using my,
while in test2.pl, the variables are defined without
use of the keyword my.
Here are the results of my attempts at running the
scripts :
% perl -c test1.pl
test.pl syntax OK
% perl -c test2.plperl -c test2.pl
Global symbol user requires explicit package name at
test2.pl line 5.
Global symbol test requires explicit package name at
test2.pl line 6.
Variable $user is not imported at test2.pl line 8.
Global symbol user requires explicit package name at
test2.pl line 8.
Variable $test is not imported at test2.pl line 9.
Global symbol test requires explicit package name at
test2.pl line 9.
test2.pl had compilation errors.

while ... continue loops
I have been programming perl for quite some time, but i have never used a 'continue' block. It seems just as easy to put any code that one would normally put in a continue right into the loop itself. What is the purpose of a continue block? Is there a time where a continue might be prefered to simply having one block for the whole loop?

Is this the code you're trying to use? Because if it is, then the problem

RE: multiple entry/exit points
Personally, i am very liberal with my lasts/breaks/returns/gotos. There is definitely something to be said for strictness. From a theoretical point of view, the code flows better. For example, it is easier to diagram and easier to debug. If i write code for the company i work for, i follow their rules, which usually means only one return statement in a sub/function and no lasts/breaks in my loops. The word 'goto' is considered profane. From a practical point of view, this sort of strict adherence to an abstract philosopy can take away from the efficiency of the program and make it more cumbersome to write. David's words are wise: q/Use your judgement based on the problem... don't stick to one philosophy or the other just because./ Well said.
